American Hazel
Corylus americana

Description

Corylus americana or American hazel is native to Ontario, and ranges from southern Manitoba to southwest Quebec and throughout most of the eastern U.S. It prefers well-drained, moist soils that are high in organic matter, but is tolerant to a wide variety of soil types and pH ranges. It is a versatile plant that can be pruned year-round and tends to sucker from the roots, requiring regular thinning. It produces edible nuts that mature in September to October and attract seed-eating birds. The tree can be moderately messy with fallen nuts, catkins, and leaves, which may require occasional clean-up. Although availability is limited in the tree nursery, this species is becoming more popular and should become more available in the future.
